Thank you for reviewing @TobiHartmann ! I think `AllocationMergesTests.java` isn't the ideal place for these tests. The tests in `AllocationMergesTests.java` are for checking the IR shape after the optimization, the current issue was actually because of a problem emitting debug info for a compilation unit - it's not something that we can capture with the IR-framework I believe.

In this other PR (https://github.com/openjdk/jdk/pull/15825) I have a test file that I think will be more appropriate for this kind of test.
